do all future leaders need 50 posts at the point of initial application?

Good question!

If the application is presented with multiple prospective leaders and one of the leaders is not at 30/50, that particular leader cannot be a leader until they meet the requirements. We may ask for clarification about who the "boss" is - so long as the boss leader is at the requirements we usually green-light!

We do check, during formation of the pack, that the submitted leader[s] are all at 30/50. If they're not, we don't promote them.

If the application is presented and there is only one leader, and that leader is not at 30/50 at the time of application, the pack idea is automatically red lit.
